Communication E²PROM write selection (Pr. 342)
When parameter write is performed from the inverter PU connector parameters storage device
can be changed from E²PROM + RAM to RAM only. When changing the parameter values fre-
quently, set "1" in Pr. 342 to write them to the RAM only. The life of the E²PROM will be shorter
if parameter write is performed frequently with the setting unchanged from "0 (initial value)"
(E²PROM write).
The above parameter can be set when Pr. 160 = 0.

Parameter values written by communica-

1
Parameter values written by communica-
tion are written to the RAM.
NOTE
When "1" (write to RAM only) is set in Pr. 342, powering off the inverter will erase the
changed parameter values. Therefore, the parameter values available when power is
switched on again are the values stored in E²PROM previously.
